what is trackr range

3. What kinds of books do you usually look at and what are you interested in?Yes (important thing to say three times) do not say that you are not interested, do not say that you have a wide range of interests, the best can be specific to which aspect , by the way, you see a book of the past, what the harvest .4, 32 The

improve efficiency ... But aesthetics is still a problem ... If it is sealed in a function ... It looks really beautiful ... But efficiency is worse than this ... Is there a more perfect solution for both? Additional... I wrote a scheme with array sorting ... Efficiency and self-realization functions are almost ..

title: Given a sorted array, find out the scope of the given target value, the complexity of the algorithm is required in O (Logn), and if not found, returns [-1,-1];Example:For example,Given [5, 7, 7, 8, 8, 10] and target value 8,Return [3, 4] .Problem Solving Ideas:When we see the time complexity O (logn), we naturally want to use the two-point method, this problem, we naturally also use a two-point method;Mid = (start + end)/2; There are three rela

Scope is for variables, for example, we create a function that contains a function, and now there are three scopesGlobal scope ==> function 1 Scope ==> function 2 scopeThe scope is characterized by first finding it in its own variable range, and if not, it will look up along the scope.Such as:var a = 1;function B () { var a = 2; Function C () { var a

An iterator (iterator) is a lazy, iterative object (lazy iterable), and the range function is an inert, iterative object in Python 3, and range is not an iterator? Why. The Range object in Tlnr:python 3 (the Xrange object in Pyt

also can represent a minimum number. This is why the 8-bit binary, which uses the original code or the inverse code to represent a range of [-127, +127], and the use of the complement expressed in the range of [-128, 127].Because the machine uses the complement, for the 32-bit int type that is commonly used in program

inferences, specifically how to achieve the CPU has to ask the designer ....Let's look at an example:Char a=-129;printf ("%d", a); How much will it be entered?? The result is 127, why?129 in the complement of 10 0111 1111 only after the eight-bit storage, that is, 0111 111 This value is exactly 127, the same as 130 after truncation

is taken out, the CPU will add the highest one, to 1 1000 0000 so that can be translated into-128 output, or 1000 0000 How to output? This is, of course, one of my inferences, specifically how to achieve the CPU has to ask the designer ....Let's look at an example:Char a=-129;printf ("%d", a); How much will it be entered?? The result is 127, why?129 in the compl

Why is the char type in the following range? In C, the signed char type ranges from-128 ~ 127. This is also written in every textbook, but no book (including teachers) will give you why-128 ~ 127. It seems that this problem is easy and easy, so you don't have to think about why. Isn't there a formula with an Integer
